Business Process, Functional and Structural Modeling

Read the following:

CRC (class-responsibility-collaboration) cards are used to document the responsibilities and collaboration of a class. In some object-oriented systems-development methodologies, CRC cards are seen to be an alternative competitor to the Unified Process employment of uses cases and class diagrams.

Responsibilities of a class can be broken into two separate types: knowing and doing. Knowing are those things that an instance of a class must can know. Doing responsibilities are those things that an instance of a class must can do.

Elements of a CRC Card, a set of CRC cards contain all the information necessary to build a logical structural model of the problem under investigation. CRC card captures and describes the essential elements a class. The front of the card contains the class’s name, ID, type description, associated use cases, responsibilities and collaborators. The name of a class should be a noun (but not a proper noun, such as the name of specific person or thing).

CRC cards can be used in a role-playing exercise that has been shown to be useful in discovering additional objects, attributes, relationships and operations. In addition to walkthroughs, role-playing is very useful in testing the fidelity of the evolving structural model.
